AGON-AXLE.-

SPECIFICATION forming part of Letters Patent No. 278,755, dated June 5,1883.

- Application filed March 19, 1883. (No model.)

T 0 all whom it may concern.-

Be it known that I, FREDERICK ULRICH, a citizen of the United States,residing at the city of Peru, in the county of Miami and State ofIndiana, have invented certain new and useful Improvements in TrussedAxle-Supports for \Vagons and Vehicles; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 ofthe drawings is a front elevation of an axle and attachmentswith my invention applied; Fig. 2, an under plan view of a portionthereof; Fig. 3, a sectional view of a portion of a thimble-skeinembodying my invention; Fig. 4, a modification of the same, and Fig. 5 amodification of the truss-connection.

This invention relates to certain new and useful improvements in thatclass of inventions known as trussed axles, the object thereof being toprovide such a device simple and inexpensive in its construction toovercome the defects heretofore experienced, and thereby effectuallystrengthen and prevent the axles from sagging or breaking when the wagonor other vehicle upon which they are used is heavily loaded, and also totighten and hold the skeins securely in place. The objects I attain bythe construction substantially as shown in the accompanying drawings andhereinafter more fully described and claimed.

In the drawings, A represents the ordinary wooden axle, provided withthimble-skeins B, said thimble-skeins having the under side of theirshoulder portion flattened and a suitable lug or projection, a,depending from their centers, other lugs or projections, b, similar inlength and height to the one a, depending from the sides, as shown inFig. 2. Extending along the under side of the axle A from skein to skeinis the truss 0, formed preferably of alink shape, with its ends'loopedaround the lug or projection a of each skein, and. secured by plates 0,having their bearings upon the lugs or projections to b, and held inthis position by nuts (1 upon the screw-threaded ends of suitable clips,6, passing through the plates, said clips passing around the shoulderportion of the skeins. The truss, being virtually slotted from end toend, admits the bolts f, which pass through the bolster D and. hounds Eand axle A, suitable washers, 9, being interposed between the truss andaxle, to increase the tension of said truss upon the thimble-skeins whenfound necessary, and the whole securely held by suitable nuts working onthe screwthreaded ends of the bolts f.

Though 1 have described the above form of thimbleskcin andtruss-connection as being preferable, the same may be modified as shownin Fig. 4, in which the truss consists of two separate pieces secured inplace between the lugs or projections to b by a suitable bolt passingthrough said truss and the lugs or projections, the lugs or projectionsbin this instance being placed in relation to the central one, a, at adistance therefrom not greater than the thickness of the piecescomposing the truss, the plates 0 and clips 0 being entirely omitted,and, if desired, the lugs or projections 12 may be also omitted. Thetruss may also be modified as shown in Fig. 5, which consists of a linkor loop having connected to its ends plates or links, which in turnconnect with a clevis attachment adapted to be secured to the lugs 0rprojections upon the thimblc-skcins, as

.shown in the modification Fig. 4.

and requires no particular mechanical skill to perform the operation,thus admitting of the tension being regulated at any time by interposingwashers of suitable thickness between the truss and axle without thenecessity of taking the vehicle to the shop or calling upon the servicesof a skilled workman and the truss being directly connected to theskeins, said skeins are at all times kept up snugly in place, therebypreventing the sagging or breaking of the axles; and the skeins beingthus kept up in their proper position, the wheels revolving thereoncannot be thrown out of position when the wagon or vehicle is heavilyloaded, this being usually the case, resulting from the sag.- ging orbending of the axles under strain, thereby increasing the liability ofthe said axles to break off close to their skeins.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. The thimble-skeins 13, formed with lugs a, in combination with thetruss 0, consisting of two bars, either separate or connected togetherinv the form of a link, said truss embracingthe sides of the lugs, andheld thereon by means substantially as shown, and for the purpose setforth.

2. The thimble-skeins B, having lugs a I), in combination witlrthelink-shaped truss C and plates 0, with the nuts and clips for holdingthe plate in position, substantially as and for the purpose specified.

The thimble-skeins B, having upon their under side lug or lugs, incombination with I the truss C, constructed as described, and the lwashers'g, interposed between the truss and axle and removabletherefrom, whereby the 15 tension of the truss may be increased,substantially as and for the purpose set forth.

In testimony that I claim the above I have I hereunto subscribed my namein the presence I of two witnesses,

- FREDERICK ULRICH.
